There is no need for the recreational PPL in New Zealand and it should not be introduced either despite what some people might say. There should not be more than one standard for the training. I am not arguing that one system is superior to an other. I am just stating that there should only be one licence for the PPL.
What is needed is another class of medical to allow people such as yourself to be able to fly with appropriate restrictions. CAA are effectively doing this now when it suits them. I know of cases where they have issued medicals with restrictions attached regarding who they can carry etc.
In fact the lower class of medical was agreed to to at a meeting held between industry and CAA several years ago. I cannot understand why they have persued the Recreational PPL.
